HEATING UNIT.

Application filed April 1, 1918,

To all whom it may concern:

Be it known that I, JACOB PI-IILIPPI, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Heating IT nit, of which the following is a full, clear, and exact description.

This invention relates to heating applianccs, and particularly to a heating unit forming an attachement to the heating system of a house either used as a dwelling, factory or storehouse.

The object of the invention is to subdivide or separate heating units of a building so that they may be placed as close as possible to the work to be done, and by this means less water can be used while maintaining the same steam pressure with a less consumption of fuel as there is no unnecessary water heated.

Another object of the invention is to provide a number of separate heating units of comparatively small capacity placed in different parts of the cellar of the building so as to provide the steam at the points desired for heating the building, and at the same time provide for the radiation of an even heat throughout the cellar for warming and drying the same, said warming and drying being the waste heat necessarily thrown out by the heating units.

In the accompanying drawings:

Figure 1 is a fragmentary sectional view through a house showing a number of radiators and pipes connecting the same with a furnace and a heating unit showing an embodiment of the invention.

Fig. 2 is a sectional view through the heating unit shown in Fig. 1, the same being on an enlarged scale with certain parts broken away for better illustrating the structure.

Fig. 3 is a transverse sectional view through Fig. 2 on line 33.

Fig. 4 is a longitudinal vertical section through the burner shown in Fig. 2

Fig. 5 is a transverse sectional view through the burner shown in Fig. 4, the same being on an enlarged scale,

Fig. 6 is an enlarged fragmentary lon-- gitudinal vertical section through the con trolling device shown in Fig. 2, the same embodying certain features of the invention.

In steam heating systems there is provided a radiator for each room, or a radiator proportioned to the volume of air to be heated, and these radiating surfaces are connected either by a single return or double return to a. steam furnace. These connections are positioned so that the steam will pass from the upper part of the steam furnace into the steam supply pipe and the condensed water will return to the bottom of the steam furnace. In arranging the furnace in an ordinary dwelling, apartment, or other building it is usually positioned at some distant point, and substantially horizontal pipes extend therefrom in the basement to different points and then extend vertically upwardly to the different rooms above. In this way steam must travel upwardly a short distance from the furnace then horizontally for an appreciable distance and thereby lose its efficiency, and then again vertically to the various radiating elements. These different bends, especially the horizontal section of pipe retards the movement of the steam and in fact causes a considerable radiation before it reaches the designed radiating elements. This loss of heat requires the use of more fuel than would otherwise be necessary, but where a number of vertical supply pipes or risers are provided at different places for a building and they are all connected with a single steam supply or boiler it is absolutely necessary to eX- tend the supply pipes horizontally or substantially horizontally to the boiler. In the present invention a heating unit has been provided which is connected to and directly below each riser and may be used in connection with the furnace or independently thereof. The same is so arranged that substantially all of the heat is quickly transmitted to the various radiators and the heat thereby radiated at the places desired. When the steam is condensed in the radiators the condensation will fall directly back into the heating unit boiling hot, thus insuring perfect circulation which it is impossible to obtain when using longitudinal runs. In this connection it will be seen that a heating system with good circulation will require less fuel than one which is faulty so that the provision of a construction and arrangement whereby the water immediately falls back into the heating unit produces maximum results, as the returned sage ofheat.

ators 6, 7 and 8 are provided for these floors,

all of said radiators being connected to a single vertically arranged riser 9 which eX- tends into the cellar 2 and to which a steam pipe 10 is connected, which pipe is also connected to the upper part of the furnace boiler 11. A return pipe 12 is also connected to riser 9 below pipe 10 whereby the returning condensed water may pass clownwardly into the bottom of the boiler of the furnace 11. A heatingunit 13 is connected to the riser 9 preferably below the connection for pipes 10 and 12 as shown in Fig. 1, a valve 14 being interposed between the heating unit 13 and riser 9. Valves 15 and 16 are interposed in the pipes 10 and 12 preferably at a point near where these pipes are connected to riser 9. If in entremely cold weather the heating unit 13 is not sufficiently powerful tosupply suificientsteam the valve 14 is closed and valves 15 and 16 opened so that steam could pass from furnace 11 to the radiators. However, in most all circumstances heating unit 13 would be suiiicient and when in use the valve 14 is opened and valves 15 and 16 are closed. However, the connection as shown in Fig. 1 issuehthat either the heating unit 13 could be used or the furnace according to the desire of the person owning the. house.

. As shown in Figs. 1 and 2, the pipe 9 connects the valve 14 with the boiler 17, said pipe extending for most of its length through the casing 18, which casing is contracted at the upper end to retard the pas- The boiler 17 may be of various types, as for instance, the ordinary porcupine structure may be provided with a central tubular section 19 supplied with a comparatively few tubular projections 20 as shown in Figs. 2 and 3, or may be provided with a large number of projections 20, with- .out departing from the spirit of the invention. A filling pipe 21 is connected to the tubular section 19 of the boiler 17, said'pipe having a valve=22 and a funnel 23 whereby I water may be supplied to the boiler 17 when- 60.

even necessary. .If preferred the pipe 21 could be connected to theordinary water 3 pressure of the city or other water supply system. A test pipe 24 is connected to the end of the boiler 17, said pipe having a valve 25 at the outer end, wherebywhen this valve is open and water is being supplied to the boiler said water will begin to flow out of valve 25 when the desired quantity has been placed in the boiler. Pipe 24 is connected to the upper section 26 of casing 27 by pipe 28 so that steam from the boiler 17 will freely enter the upper section 26 whereby the steam may freely act on the diaphragm 29. If the chamber 30 in'the section 26 should not be filled with water no damage would be done and the steam. from boiler 17 passing through pipes 24 and 28 will act thereon so that pressure will be transmitted to the diaphragm 29, which diaphragm may be of rubber or metal as preferred. A bearing plate 31, preferably of metal, is preferably rigidly secured to the diaphragm 29 by any suitable means, as for instance screws as shown in Fig. 6, and receives the pressure of spring which. acts against the plate and against partition 33 of the casing 27. This spring acts to keep the diaphragm 29 and the plate 31 in the position shown in Fig. 6, whereby the plate 31 will be out of contact with the tubular member 34 and consequently gas may pass through the supply pipe 35 and into chamber 36, and from thence into pipe as indicated by the arrow in Fig. 6. From pipe 34 the gas passes into the chamber 37 and then out the pipe 38. In case the steam pressure increases to an undesirable extent said pressure will act on diaphragm 29 and move the same downwardly or toward the tubular member 34 so that the plate 31 will then act as a valve member for reducing the passageway for the gas or for entirely shutting off said passageway. If the pressure should become sufficiently great the plate 3]. will press tightly against tubular member 34 and completely shut off the gas so that burner 39, hereinafter fully described, will be deprived of fuel until the steam pressure has been reduced. To prevent the burner 39 from being completely deprived of gas a bypass 40 is provided which supplies enough gas to leave, What may be termed a pilot flame, until an additional supply is provided by the plate 31 leaving tubular member 34. In order to regulate the supply of gas manually, in addition to this automatic regulation or shutting --ofl', the tubular member 34 is provided with site direction will increase the supply of gas, orwill open the passageway to a greater extent so that more gas will flow in. When the gas passes into pipe 38 it is discharged into burner 39 after passing through the usual mixer 43 which is of the Bunsen type for supplying proper combustible mixture to the apertures or jets in the burner 39. The

burner 89 usually is a straight pipe having a plurality of apertures tt on the top so that the flame will be more or less spread. Retarding members 15 and 16, preferably of the same size, are mounted in the pipe forming burner 39 so as to retard the combustible gas passing therein and causing even dis tribution thereof. The air and gas entering the burner moves with some considerable velocity and if the pipe was perfectly free the larger supply of gas would be for the apertures nearest the outer end l7. By providing the rings and i6 the flow of gins is checked by the restricted passageway, consequently a substantially even supply is provided for all of the apertures so that the boiler 17 is substantially evenly heated for its full length.

In order to prevent any of this heat from escaping, or limiting to the largest possible extent the radiation of heat, a casing 48 is provided, preferably of metal, which fits over the boiler 17 and to which the sleeve 18 is secured. This metal casing is also preferably provided with an asbestos covering. By this construction and arrangement it will be seen that substantially all of the heat. units are transmitted to the water in the boiler, or to the steam, and that the steam is super-heated to a considerable extent by the fact that the heat from theburner 39 will pass around the upper part of the boiler 17, through the sleeve 18 and eventually out the restricted opening 49. In this way the steam leaving the boiler is heated to the greatest possible extent, and also the returning condensed water will be heated to a certain extent as it passes downwardly through riser 9 into the boiler 17. The boiler 17 and associated parts are connected to the riser 9- directly in line therewith so that as the hot vapors rise, and as the steam is generated said vapors and steam will immediately pass upwardly as there is nothing in the way to retard said passage until the takes place so that a maximum number of heat units generated is used at the point desired, namely the radiators of the various rooms. The heating unit may be supported by riser 9 or may be supported by any suitable bracket, as for instance bracket 50 shown in Fig. 1.

WVhat I claim is:

A heating unit for a heating system comprising a. horizontally elongated casing having end plates and provided at its top approximately midway between its ends with an upwardly projecting extension-casing communicating at its lower end with the interior of the casing and having its upper end contracted, a horizontally elongated boiler within the casing and spaced therefrom, a riser pipe extending upwardly from the boiler, the riser projecting upwardly from the boiler through the extension-casing and above the contracted upper end thereof with said contracted end spaced slightly from the riser, a burner tube extending within the casing below the boiler, the said tube being secured at one end to one end plate of the casing and projecting at its other end beyond the other end plate of the casing, the portion of said burner tube within the casing being provided with a retarding member or members, a test pipe connected to the end of the boiler and projecting through the casing and beyond the same over the outwardly projecting end of the burner pipe, a governor with which said test pipe communicates and means whereby the governor controls the passage of gas to the burner tube, all substantially as and for the purposes set forth.
